Tab sis koj yuav tsum paub yuav ua li cas mus saib hauv lub nozzles kom zoo.

Manifestation ntawm nozzles malfunctions

Yog hais tias lub cav tsis ruaj tsis khov, nws yog tsis yooj yim sua hais tseeb dab tsi raws nraim qhov ua rau ntawm malfunction. Ib tug kev daim ntawv ntsuam xyuas: coils, taws tswm ciab, compression engine, etc ...

Ua ntej koj yuav mus saib lub injectors, soj ntsuam seb puas muaj ib tug nram qab no yuam kev:

1. Tsis ruaj tsis khov idling.
2. Teeb meem nrog tus pib.
3. Ib tug ntau dua kev noj roj.
4. Poob ntawm puab, tsis muaj hwj chim thaum lub sij hawm acceleration jerks thaum lub caij.

Yog hais tias cov teeb meem no tshwm sim nrog koj cav, ces nws yog lub sij hawm mus xyuas qhov tseeb lag luam ntawm lub injectors. Muaj ntau txoj kev mus xyuas rau lub engine nozzle. Manufacturers ua lawv zoo tshaj plaws los pab txhawb cov kev nkag mus rau feem ntau "tsis muaj zog" tsheb rooj. Yog li ntawd hais tias cov teeb meem yuav tsum tshwm sim.

Yuav ua li cas mus saib hauv lub injector nrog ib tug multimeter?

Muaj yog ib tug tshwj xeeb lub cuab tam rau diagnostics - multimeter. Nws yog pheej yig, thiab muaj nyob rau txhua qhov kev pab chaw nres tsheb. Nrog nws feem ntau yog mus saib roj teeb, fuses thiab lwm yam hais txog lub hauv combustion engine system. Cov lus qhia yuav ua li cas mus saib hauv lub nozzles vases thiab lwm hom ntawm lub tsheb:

1. Qhib phau ntawv thiab saib uas nozzle yog siv nyob rau hauv koj lub tsheb - yog qis los yog siab impedance. Nws yog tsim nyog rau ib tug muaj tseeb kuaj mob.
2. Tshem tawm cov hlau los ntawm lub nozzles.
3. Siv ib tug multimeter thiab teem nws nyob rau hauv cov kuj ntsuas hom. Diagnostic hlau Tam sim no tsiv mus nyob rau cov lus xaus ntawm lub nozzles.
4. Ntsuas cov kuj.
5. Nruab nrab kuj tsawg impedance injectors yuav tsum 2-5 ohms. Cai nyob rau qhov siab impedance injectors - 12-17 ohms.

Yog hais tias lub multimeter koj nrhiav tau qhov tseem ceeb uas tsis haum nyob rau hauv lub teev ntau, nws txhais tau tias injectors uas ib yam dab tsi yog tsis ncaj ncees lawm. Feem ntau, ib yam khoom uas tsis sib tau lub cev kuj yog muab tshem tawm thiab hloov nrog ib lub tshiab.

Nco ntsoov tias ib tug multimeter - ib tug tseem ceeb ntaus ntawv, uas yog nyob rau hauv tej tswv, koom nyob rau hauv electronics. Nrog kev pab los ntawm kev ntsuas voltage nyob rau hauv lub tshuab hluav taws xob Circuit Court, cov kuj hais. Yog hais tias tsim nyog, yuav ib yam ntawm cov kev ntsuas, vim hais tias nyob rau hauv txhua rooj plaub nws yuav tsum thaum xyuas ntau yam ntawm lub cav.

Xyuas los ntawm lub pob ntseg

Cov neeg tsav tsheb paub yuav ua li cas mus saib hauv lub nozzles rau diesel los yog roj av cav los ntawm lub pob ntseg. Lawv tsis txawm xav tau ib tug multimeter. Inexperienced tsav tsheb ua rau nws tsis yooj yim, tab sis koj yuav tau sim. Ua tib zoo mloog zoo li cas suab emanate los ntawm tus kheej kheej block. Ringing suab ntawd hais tias cov injector yog tsis ua hauj lwm kom zoo, ces lawv yuav tsum tau mus soj ntsuam thiab ntxuav. Ntawm cov hoob kawm, tus raug ntawm no txoj kev ntawm mob yog tsis tsim nyog los piav qhia. Nyob rau hauv tsawg zaum nws yog tau los yog tshawb nrhiav qhov teeb meem los ntawm lub pob ntseg.

Kuaj txhua yam khoom

Nyob rau hauv thiaj li yuav tau soj ntsuam xyuas cov ntsiab xav tau tshwj xeeb cov cuab yeej, ces nws yog ib qhov nyuaj rau koj nqa tawm nyob rau hauv lawv tus kheej. Feem ntau cov garages muaj stands mus xyuas lub stability ntawm lub nozzles, thiab lawv muaj peev xwm nrhiav tau, uas cov xov no yog tsim thaum ua hauj lwm. Hais tias yog, koj yuav visually soj ntsuam cov "teeb" txau roj av (diesel roj). Yog hais tias lub roj tsuag tusyees, teeb meem nyob rau hauv internal combustion xyaw yog heev sai tau.

Nws yuav tsum tau muab sau tseg hais tias qhov no yog cov feem ntau muaj tseeb, thiab nws yog guaranteed qhia ib tug txhaum.

tu injectors

Yog hais tias thaum lub sij hawm tus mob qhia hais tias cov ntsiab tsis ua hauj lwm zoo, ces koj yuav tsum tau ntxuav lawv. Koj yuav tau ua qhov no rau lawv tus kheej, tsis tshem lawv los ntawm lub engine.

tu kev xaiv:

1. Siv ntawm additives rau lub engine. Lawv sau nyob rau hauv ib tug roj tank, tov nrog roj, thiab thaum twg nws kis los ntawm tus nozzle, ntxuav lawv additives.
2. Ib txhia txog tej neeg tsav tsheb yog pom zoo kom ua tau ib tug txhua hli tu nrog kev pab los ntawm siab. Ua li no, koj yuav tsum mus disperse lub tsheb mus rau ib tug ceev ntawm 120 kilometers ib teev nyob rau hauv ib tug ca txoj kev. Nyob rau hauv no hom nws yog tsim nyog los dhau txog 10 kilometers thiab qeeb.
3. Yog hais tias koj tsis muaj peev xwm li cas los xij mus ncig teb chaws thaum ntawd ceev, ces ua tib yam txheej txheem yuav tsum tau nyob kaw. Zog yuav tsum tau khaws cia nyob rau theem ntawm 4-5 txhiab. Nco ntsoov tias txoj kev no yog tsawg npaum nyob rau hauv kev sib piv nrog rau cov saum toj no.

Txawm yog hais tias tus cav khiav tsis tshwm sim yuav tsum tau muaj teeb meem, cov injector yuav tsum tau ntxuav txhua txhua 35-40 txhiab kilometers raws li ib tug tiv thaiv kev ntsuas. Noj rau hauv tus account qhov zoo tshaj ntawm petrol, uas yog fwj rau hauv ntau lub roj noj, lub nozzle - nws yog ib qho lub caij, uas yog ib tug ntawm cov thawj yuav tsum tau kev kho los yog hloov.

Qhov zoo ces, tam sim no koj paub yuav ua li cas mus saib hauv lub lag luam los ntawm cov injectors, thiab kho lawv yog hais tias ua tau.
